![]() ![]() Based on the network topology above, it is VLANs 10, VLAN 20, and VLAN 30. Step 2: Take note of the VLANs that must be routed. ![]() Even though this command is usually enabled, it does not hurt to be certain that it is. Step 1: Enable routing capability on the switch. In this simple Inter-VLAN routing scenario, we will be using a Cisco Catalyst 3550 as our Layer 3 Switch. How to Configure Layer 3 Switch InterVLAN Routing?īelow is a diagram that we can use as a reference in understanding how to configure Inter-VLAN routing and test inter-switch connectivity across the network before configuring its routing capability. Layer 3 switches convert a Layer 2 switch interface to a Layer 3 interface, making it a routed port similar to a physical interface on a Cisco IOS router. Cisco Catalyst 4500/4000 Series with Sup II+ or laterĪ Layer 3 Switch can route from one VLAN to another using multiple Switched Virtual Interface (SVI).Below are some of the Cisco Catalyst Series switches with Layer 3 functionalities: The latest Cisco Catalyst Switches are equipped with the Enhanced Multilayer Image (EMI), which can work as a Layer 3 device with full routing capabilities, also known as a multi-layer switch (MLS). ![]()
